FEE D-GUIDlE ATTACHMENT FOR KNITTING-MACHINES.

PECIFIGATION forming part of Letters Patent No. 279,380, dated June 12, 1883.

' Application filed November 11, 1882. (No model.)

To all whom it may concern:

Be it known that I, PETER I. HARVEY of Amsterdam, in the county of Montgomery and State of New York, have invented a new and Improved FeedGuide Attachment for Knitting-Machines, of which the following is afull, clear, and exact description.

The object of my invention is to provide a new and improved feed-guide attaclnnent for knitting-machines, whereby one of thethreads can be passed above the other at will, the raised thread showing on the outer surface of the knitted fabric.

This invention is an improvement on the circular-knitting machine for which Letters Patent No. 253,531 were issued to myself and to my assignees, Augustus Clark and Perry Kline, of Amsterdam, New York, on February Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar letters of reference indicate corresponding parts in both the figures.

Figure l is a plan view of part of a knittingmachine provided with my improved feedguide attachment. Fig. 2 is aside View of the feed-guide attachment, showing the manner in which it is attached to the feed-stand.

My invention is applicable to the ordinary upright circular-knitting frames, which frames are well understood by those skillful in the art of knitting, and it will not be necessary The feed-stand F has attached thereto the,

cloth-presser wheel G, the loop or sinker-burr H, and the fixed feed-guide I, and are all adj ustable in their relative positions in the usual manner and on the same pivot which secures the thread-guide Ito the feed-stand F. An additional feed-guide, W, is pivoted to the feedstand F, which pivoted feed-guide IV is parallel with the fixed feed-guide I, but has its end at the needlecylinder inclined toward the corresponding end of the feed-guide I, as shown in Fig. l, the end of the feed-guide \V projecting slightly beyond theend of the feed-guide I.

A spring, V, surrounding the pivot of the feed 5 5 guide WV, presses the said feed-guide W in a horizontal position.

In place of the spring V, any other suitable device can be used which will keep the feedguide W in a horizontal-position orreturn it to the same after it has been moved out of the said horizontal position. The pivoted feedguide \/V is provided with a downwardly-projecting arm, U.

011 the stand L, I place the cam ratchetwheel M, which is provided with one or more cams, c. Upon the ratchet-wheel I place the adjustable cam-lever f, which vibrates upon a stem, and is held in its normal position by the spring Z. The combined ratchet and cam wheel M is prevented from revolving backward by the pawl-spring on. As the cam c presses the lever p forward the end of the latter rides upon the outer face of the cam until said end has been passed by the cam, and the lever 11 transmits motion to a lever on the opposite side of the needle-cylinder, as described in my Patent No. 253,531. The yarn is fed by the loop-wheel beneath the barbs of the needles.

The operation is as follows WVhen the cylinder A rotates it causes the lever. f by the cam E, to rotate the combined cam andratchet M in the direction of the arrow, whereby the cam 0 will press one end of the compound-lever 1) in the direction toward the cylinder, thereby pressing the middle joint of the lever 12 in the direction from the cylinder A, the other end being pressed toward the cylinder A. If the lever 19 is moved toward the cylinder A, it strikes against the arm U of the pivoted feedguide V and raises that end of the feed-guide from which the thread passes to the knittingcylinder. As long as the said feed-guide WV is raised the thread passing throughthe said feedguide XV will show 011 the outside ofthe fabric, 5 and as soon as the lever 12 is moved in the direction from the cylinder A by a spring or other suitabledevice, the arm U of the feedguide V will be released and the spring V will throw the feed-guide IV back into the horizon- 0c tal position, and the thread passing through the feedguide I will show on the outer surface of the fabric. Thus, by varying the number, size, and arrangement of the cams E and c various different designs can be produced in the knitted fabric.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A need1e-cy1inder provided with one or more cams, E, combined with the fixed feedguide I and the pivoted feed-guide IV, having an arm, U, and with devices for movingthe pivoted feed-guide by the action of the cams E 011 the said cylinder A, substantially as herein I 5' shown and described, and for the purpose set forth.

2. The needlecylinder provided with one or more cams, E, combined with the fixed feedguide I and the pivoted feed-guide WV, having 20
